Phoenix weather: Slight chance of showers today, tomorrow

A low-pressure system moving across the Valley should bring a slight chance of showers Tuesday, but those chances should dwindle toward the end of the week as the system moves east, weather officials said.

There is a 20 percent chance of showers in the afternoon Tuesday and a 10 percent chance in the evening before clearing up Wednesday. On Thursday there is a 10 percent chance of showers in the Valley throughout the day, according to the National Weather Service.

“If there is shower activity, that may reduce visibility a little,” said Charlotte Dewey of the National Weather Service. But the showers should be brief and more likely to affect the north Valley, she said.

Most of the system is sweeping over the Las Vegas and northern Arizona area.

Temperatures at Phoenix Sky Harbor International Airport are expected to peak at 84 degrees. The normal high for Tuesday is 92 and the record high was 108 degrees in 1999, Dewey said.

Wind speeds should be mostly calm in the Valley but Cave Creek and the areas north could see 15-20 mph gusts, Dewey said.

There is a 50 percent chance of rain in Flagstaff Tuesday afternoon that should drop off to 40 percent by Tuesday evening, according to the Weather Service. The high was forecast at 55 degrees with a low of 33.

A hazardous weather outlook was issued for the Mogollon Rim area because of possible rain showers and wind gusts, Dewey said. The warning is expected to last until midday Wednesday.
